IMPROVEMENT IN BLOW-turns.

The Schedule referred to in these Letters Patent and making part of the same 1,'J. BURRows HYDE, otthe city, county, andy State'of New York, have invented certain Improvements iu Blow-pipe Tables, of which the tbllowing is a specification.

My invention relates to the construction and arrangement of an apparatus'ior certain mechanical, chemical, and other operations, where heating and blow-pipe manipulations are required, and consists of a working-table orbench, combined with an apparatus for carbureting atmospheric air or commercial gas, and also with a bellowsor other contrivance for employing` and controlling a current or currents of air' in tubes, the gas, or carburetiugapparatus for producing the gas, being used and further combined with a blowpipe, orpther contrivauce for soldering, melting, softening, molding, boiling, or heating, as may be rcquired; (See drawing.)

a shows the table, provided with a narrow projecting upright strip, b, at the back side.

c shows an inclosing ease, which may be dispensed with, for the carbure-ter d.

e is the bellows, represented double in the drawing, and worked by a trcadle, f, and intermediate connecting-rod, g, although any other convenient mode for producing the air-currents may be used.

'lhis'bellows or blowing apparatus is provided with two outlets for vthe air, h and i, from one of which, It, a pipe, I, leads to the carbureting-vessel, (I, containing` theearbureting iuid or hydrocai'bon, the vapors of which, combining with the air, produces commercialgasfwhich escapes from thevessel el, by an outlet-tube, on, that leads to and is connected with a fixed tube, n, secured to the back l) of the table.

This tube u has connected to itv a branch orunion tube, o, projecting'therefrom. t

The second bellows-tube, i, leads to another tube,

j), also xed to the table back, b, which tube is connected with a second brauch of the union', o, having this, the air-tube, inside of the gas-tube, to eachot' which separate tubes, other or prolonging tubes, are attached,'and connected with the burner 0 1' nozzle, as indicated inthe drawing, aud-for which I prefer to use elastic tubes, one within the other, but other contrivances, may be-used for this purpose. I also prefer that. the air-tube be inside that for the gas, and that both the 'gas' and the air should unite as' near the outlet of the burner as possible.

In using ordinary commercial gas with this apparatus,.the outlet h ot the bellows is dispensed with, and the tube l, to be attached to a pipe conveying that gas, which, iiowinginto the carburetor, will be improved in quality, and greatly economized in use.

It will be well. to have in each of the tubes t and I a stopor regulating-cock, to graduate the ow ot' air from the blower,'according to the diierence oi' .pressures required.

l. The apparatus described, for the purposes set forth. p v

2. The use of a blowing contrh-'aue-e, with two airconductors, in combination with an air or gas-carburetor, and a blow-pipe or heating contrivance, as described, and for the uses set fort-h.
